SPECIFICATION forming part of Letters Patent-No. 731,006, dated June 16", 1903. Application filed September 26, 1901. Serial No. 76,636. (No model.)

To all whom, it. may concern: v

Be it known thatLJAooB WOLEENSPERGE a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Windows; and I do declare that the following is a full, clear, and

exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in windows; and the invention consists in a window provided with reversible window-sashes and with parts associated therewith adapting the sashes to be reversed within the windowcasing for washing, all substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is an outside elevation of a window equipped with my invention. Fig. 2 is a vertical sectional elevation thereof from front to rear; and Fig. 3 is a plan view in section on line Y Y, Fig. 2. Fig. 4 is a vertical sectional elevation on line Z Z, Fig. 5; and Fig. 5 is a vertical sectional elevation on line X X, Fig. 4. Fig. 6 is a detail of. the locking mechanism. Fig. 7 is a detail of one of the slides.

In the drawings thus described, A represents the window-casing, which is designed to be constructed with respect to the uses of my invention, and B and C respectively indicate the upper and lower sashes of the window. In this instance I show a window with two sashes; but it should be understood that the invention is adapted to work with a' single sash as well as with two and that in the main it amounts to a duplication to employ the twosashes.

To this, however, there are some minor exceptions, which will appear in "constructed and adapted to operate in conjunction with the associated mechanism, substantially as herein shown and described.

Referring now to the lower sash C, it will be observed that the said sash is provided on each side with a trunnion 2, Fig. 3, which rests in a suitable box or bearing 3 withinthe casing, said casingjbeing recessed to receive the trunnion and the box, if necessary, and an open inclined slot 4 leads from the front of the casing into the said bearing, and this construction is common to both bearings 3. The casing A is further shown as constructed with its inner side flush from front to rear, as indicated by the front and rear inner surfaces, (marked 5 and 6, respectively,) and the edge of the sash is designed to fit snugly on this inner surfaceof the casing both above and below its trunnions or pivots 2, and by reason of this surface being flush across on both sides the sash is free to swinginto inclined position and to be reversed, as indicated in dotted lines, Fig. 2. However, in front of the immediate bearing orside portion of said casiug'for the sash there is a vertical channel the full depth of the casing, adapted to receive slides D, one

on each side, (shown in detail in Fig. 7,) and provided with a shoulder 7, adapted to receive and carry the trunnion 2 when the sash is lifted out of its seat onto its slides. The said slides are each provided with cords 8 and counterweights 9, adapted to counterbalance the sashes and make them free to be run up and down the same, as ordinarily occurs with counterweights in windows. However, in this case the window-sash itself is not counterweighted nor is itintended to be raised directly up from its normal position, as seen in Figs. 1 and 2; but in order to be raised it must first be lifted forward to rest its trunnions in the slides D. This being done and raising the sash and its slides-a little way carries the trunnions past the slots dand enables the sash to be operated practically as the ordinary sashes are when they are counterweighted to balance them and to raise and lower. One important advantage of thisconstruction is that when the sash is in closed position, as in Figs. 1 and 2, it is physically impossible to raise itlirst, because it abuts directly against the upper sash B, and, secoudly, because its trunnions are so located and engaged that raising it directly upward is impossible. This makes the sash absolutely burglar-proof, so far as raising it or displacing it is concerned, provided that no brakage occurs, to enter. When the sash is in its normal place, as described, any suitable lock may be employed to prevent swinging it on its pivots or trunnions, and such lock may be at the point where the two sashes come together and where they overlap, as seen in cross-section, Fig. 2, or at any other convenient point by any'convenient means, such as a bolt, a sash-lock, or other device of that kind. It thus occurs that when the lower sash is liberated from any lock provided to secure it and the parts are related and arranged, say, as in Fig. 2,it can be swung into position, as in dotted lines, Fig. 2, and reversed by simply pressing outward against its bottom. This also enables one to take hold of the sash and raise it into position to engage the slides D when it comes inside of the abutting shoulder 11 of the sill-board 12 and makes it free to be wholly reversed in position, so as to bring its outside in into perpendicular position. Springs 13 are shown to engage shoulders on the slidesD and hold them in their'lowered position ready to take the trnnnions 2 when the lower sash is to be shifted, as hereiubefore described.

The upper sash I3 is adapted to be rotated and reversed and shifted in the same manner and by the same means as the lower sash C, and the same reference characters are employed to designate the parts associated as weather-strips and are adapted to make a very close and neat fitting engagement against the rear faces of the sashes when the sashes are closed, as seen in cross-section, Fig. 3, and by the operating mechanism for controlling the position of these uprights they can'be pressed very closely against the sashes and make them storm-tight. However, if preferred, a suitable felt, rubber, or other packing or cushioning strip 14: may be interposed to make the joint perfectly tight. The

I said posts or uprights, therefore, have flat faces to rest against the sashes, and the easing A has vertical recesses 15, in which they are adapted to berotated bodily in order that.

the sashes maybe free to swing on their pivots.

The said uprights are supposed to be swung out of the way in Fig. 2 when the sashes are swung into inclined position, as is shown in dotted lines therein; but in Fig. 3

they are in their normal and working position. When in this position, it likewise is impossible to open either sash, because the sash cannot be swung on its pivot, and neither sash can be raised or lowered while these posts are in their closed position. For the control of the said posts G, I may employ any suitable mechanism connecting them or operating them separately, as I may elect. In the present case I show a lever L, having a pivot 16, adapted to slide laterally in a slot 17 and connected at equal distances from its pivot by means of rods 18 with short arms 19 on the said posts. This operating mechanism for the post G is in the bottom of the main casing, wholly inaccessible from without and controlled by lever L on the inside. Any suitable means may be employed to lock this lever, and I show a series of catches on a locking-plate 20 in the present construction, Fig. 6. The slot 17 for the pivot of operating-lever Lrenables the pivot-point to change position one way or the other, according to the position of the uprights G, so as to bring both said uprights tightly against the window, though they may work somewhat differently from each other, and the pull of the lever is thus equally distributed as to said parts.

To open, say, the lower sash, first turn or rotate posts G by means of lever L, so that they will be swung back into their recesses 15 in casing A.- This leaves the rear of the window clear of any obstruction for the said sash. If the sash be otherwise locked or confined, release such lock also. The sash can now be rotated on trunnions 2, as they rest in bearings 3. Then having slides D in place to receive pivot-s or trunnions 2, as in Fig. 5, press against the bottom of the sash and swing it back somewhat, so as to be able to grasp it below. Then give'it a forward and upward lift to clear board 12 and get into slides D, and once in the slides raise the sash a little to carry the pivots 2 past slot 4. When the sash is shifted to rest its trunnions 2 in slides D, springs 13 are forced. back by the trunnions. This done, the sash can be easily raised and lowered or swung into reverse position, as maybe desired. It washing is not required,the sash can-be run as high as wanted for ventilation, and it can be used with window-screens with as much convenience as other windows.

The upper sash is reversed in the same manner substantially as the lower one and also is adapted to take slides D and to be run down in front of sash C, if desired. An abutting cross-strip 22 serves as a stop for the upper sash at its top outside.

What I claim is- 1. In windows, a sash having pivots at its sides on which it is adapted to be reversed,

and a setof slides at the front of said pivots constructed to receive the pivots and raise and lower the sash, substantially as described.

2. The window-casin g having vertical channels at each side, upper and lower sashes pivotally mounted in vertical alinement outside of said channels and adapted to be shifted inward into said channels, movable rotatable posts on the outside of said sashes on each side of the window-casing adapted to rest flush against both sashes, and means inside the building connected with said posts and adapted to turn them to open and closed position, substantially as described.

3. The window-casing having vertical channels in its opposed sides, upper and lower sashes having trunnions adapted to travel in said channels when said sashes are shifted thereto, and counterbalances for said sashes, in combination with vertically-mounted rotatable posts arranged to be turned against the outer edges of said sashes, and means connecting the lower ends of said posts and constructed to lock the posts together against said sashes when in closed position, substantially as described.

4. The window-casing having a bearing at each side for pivots, of a window-sash and a vertical channel at the front of each bearin g and open thereto at said bearing, in combination with slides in said channels and a window-sash having pivots engaged in said slides and adapted to be moved into said bearings, substantially as described.

5. In windows, a set of window-sashes having each a set of pivots on which it is adapted to be turned in the said casing and bearings in said casings for said pivots, and a counterweighted slide in each side of said casing in front of said sashes adapted to receive the pivots of either sash, substantially as described.

6. The casing and a window pivotally edges of said window, a lever pivotally supported on said casing and having a lateral play at its pivot, links connecting said lever with said weather-strips, and a locking device to hold said weather-strips when rotated, substantially as described.

7. The window-casing having a window pivotally mounted therein, in combination with rotatable weather-strips mounted on said casing opposite the face edges of said window, a lever and a support therefor provided with free pivotal connections adapting said lever to shift laterally on said support, and a locking-plate having a series of teeth to hold said lever in shifted position, substantially as described.

. 8. The movable window and its casing, in combination with rotatable weather-strips mounted on said casing opposite the face edges of said window and provided with an elastic cushioning-strip the full length at one side thereof, means to rotate said weatherstrips whereby said cushioning-strips are brought into engagement with the face of said window, and means to lock said Weatherstrips and the cushioning strips tightly against said window-face, substantially as described.

9. The movable window and its casing, rotatable weather-strips mounted on said casing to engage said window, means to rotate said weather-strips comprising an equalizing-le- Ver and links connecting said lever to said weather-strips, said lever having a free lateral play between the links connected thereto, and locking mechanism to hold said lever in its shifted positions, substantially as described.

Witness my hand to the foregoing specification this 2d day of August, 1901.
